Devices cannot be found on the network via wifi or hard-wired.

Unfortunately, there’s not enough information to tell. Have you called Sonos Support directly to discuss it?

When you speak directly to the phone folks, they have tools at their disposal that will allow them to give you advice specific to your network and Sonos system.

I have spent approximately 10 hours in total on this 3 with support.  They have me restarting my phone and resetting my modem.  It isn’t any of those things, it is their product which does not perform as advertised.  It should not take over 10 hours to set up a single device.

If after 10 hours you cannot get the Play 1 to connect, there must be a hardware issue.

Have you had the speaker connected to your network before, or is this a used speaker you have just purchased?

Have you tried resetting the speaker, then connecting it a cable to your router before powering it up?

Which app are you using? have you tried the PC app?

Agreed, it shouldn’t. But the people in this community don’t know what issues you’re facing. Or if it’s even working still, given that it is ‘old’ tech, only Sonos support will be able to determine that. The PLAY:1 hasn’t been made since the Sonos One came out, back in 2017. For what it’s worth (and not at all for you), I have several, which still connect just fine, in use, both as surround speakers, and as separate rooms. All running S2, but I’d assume they’d all work under S1 as well. 
 

If you’re looking for more input from the community, there’s a wealth of info about method of connection, type of network, and what has been already tried that would be useful in coming up with potential avenues to attempt. But you haven’t provided anything but ‘I have X, and it doesn’t work’…not much to go on. Although now we know you’ve spent 10 hours with Sonos support…which makes our chances all the less likely to be helpful, as they have access to much more hard data than we do. 

To date, I have spent over 24 hours of tie trying to set the Play 1 up.  At about hour 12, with the help of tech support via phone  it support It worked.  Afterwards I had to disconnect the Play 1 from the power source and now I cannot get the device to connect to the wifi network or when it is hardwired.  I can step through the set-up process fine up to the point where it asks to connect to the network.  After several attempts to connect it just tells me to restart the device.  Through all of my wasted time trying to set he device up, I have restarted it, performed numerous factory resets, reset my modem, etc.  This device has connected and work on my Google wifi network in the past just fine.  I relocated everything from the US to Italy - is that the issue?

Whether there is support within the community or not, it should not take this kind of effort to set-up a system.  A product like this shouldn’t make it’s user community go through this time suck.  It is only natural to feel poorly about the product, and about myself for being so ineffectual - especiallly when people in the “community” say things like “it isn’t that hard”, or “there is support available”.  I’m not a dunce, so don’t assume that I am.  In my case it is that hard and the support does not address my situation at all.

And, Airgetlam, the issue is not that I don’t provide enough information.  I have provided information to tech support and on-line support chats repeatedly.  Here is all the info you need:  I relocated the wifi network and Sonos from the US to Italy, my wifi network works fine.  I stepped through the Sonos set-up process but the Play 1 will not connect to the networ via wifi or hardwired with an ethernet cable to the router.  Don’t victim blame - the product is poor, not my information.

To Pools-3015,

How would the PC App help me if the speakers aren’t connected and on net?  The message on the web app is “Your speakers are offline, please turn on your speakers”.  How is that helpful?
